BOILER FOR COOKING-STOVES.

Specification of Letters Patent No. 9,766, dated June '7, 1853.

To all whom t may concern:

Be it known that I, R. IV. BELsoN, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented an Improvement inCulinary Boilers, and that the following is a full, clear, and exactdescription of the principle or character which distinguishes it fromall other things before known and of the usual manner of making,modifying, and using the same.

In describing my improvement in boilers for stoves, I will premise thatI am aware that such boilers have for some years been provided with anescape tube, to conduct the steam and odors into the chimney or flues ofthe stove, andthat my present invention is an improvement upon suchboilers. llVhen the tube is open into theboiler, before the boilingcommences, the smoke from the stove is apt to pass into the boiler. Thisoccurs whenever the draft of the stove is feeble, or a great amount offuel is thrown on to the fire at once, or when the cover is suddenlyraised; and when the cover of the boiler is off, the smoke may escapeinto the room. To obviate these defects, I employ on the top of saidtube a valve, so constructed and arranged, that, it may be controlled bythe movements of the cover of the boiler, so that when the boilingcommences, and the cover is tightly in place, the valve shall be liftedfrom its seat, and the tube open for the escape of the steam. When thecover is entirely removed, the valve is closed by its own weight. If thecover is placed lightly on, as it may be before boiling commences, thenthe valve may be only slightly open; or if the cover is placed unevenlyon, the side or edge next the valve being raised up, then the valve willbe closed entirely; and as soon as steam begins to form, and the odorsescape into the room, then the cover must be shut down closely, and thevalve will be opened accordingly. All this will be readily comprehendedby reference to the drawings, in connection with the following briefdescription.

Figure l, is a sectional elevation; Fig. 2, a top view. l

In Fig. l, (a) represents the cover in its position of closely fittingthe boiler and opening the valve, (e,)-(b,) is the boiler of commonform. (0,) is the escape tube, as usually made; and (6,) is the valve.This valve is hinged or pivoted at (iu), and has a winged portion, onthe opposite side of the pivot, which comes into contact with the edgeof the cover whenever the cover is depressed. The pressure of the coverupon this wing raises the valve; and when the cover is removed, thepreponderance of the weight of the valve over the winged portion, bringsthe valve down upon its seat, and closes the tube. rlhe valve may benicely balanced, and made selfacting; but I find the present method ofregulating the valve by the cover more reliable; and in fact it isinfallible.

What I claim, therefore, is-

'I'he employment of a valve, in combination with the escape tube ofculinary boilers, such valve being controlled by the cover, or in anyequivalent manner, substantially as herein set forth.
